Edge's village was attacked by vampires shortly before the Higheast Rebellion, and his older sister was taken away. Viktor and Flik had come to the village to investigate rumors of vampire sightings and immediately went to dispatch the vampires. Edge wanted to come along, and was lent the Zodiac Sword (Star Dragon Sword) by Viktor when he told Viktor he wanted to become an independent great swordsman. Edge killed the head vampire, rescuing his sister. Viktor and Flik then left the village upon hearing of the Harmonian Army invading Dunan, and Edge was allowed to borrow on a more lengthy basis the Zodiac Sword. He thinks highly of Viktor and his carefree attitude, and tries to improve his skills to become like him. In Le Buque, he is recruited into the Fire Bringer by Geddoe. After the events of Suikoden III, he ventures off to the south to vanquish another foe sought by the Zodiac Sword. - KoRnholio
